Key Features
- Genuine OEM Construction — Manufactured to Husqvarna's exact material and dimensional specifications, delivering the same locking strength and retention as the original factory component.
- Direct Drop-In Replacement — Engineered to match the original mounting interface, this lock installs in place of the worn or damaged unit with no rework required.
- Broad PG-Series Compatibility — Fits a wide range of Husqvarna planetary floor grinders, including the PG540, PG450, PG510, PG510I, PG690, PG690P, PG680RC, PG690RC, PG820RC, PG830, PG830P, PG830RC, and PG830S.
- Maintains Secure Component Retention — A functioning lock keeps critical assemblies positively engaged during operation; a worn or failed lock can allow unintended movement and interrupt grinding performance.
- Operational Safety — Locking components on floor grinders secure tooling, guards, or adjustable assemblies in position, making correct part condition directly relevant to safe machine use.
A lock on a planetary floor grinder serves as a positive retention device that holds a component — such as a tool head, adjustable arm, or disc assembly — firmly in its set position during operation. When the lock is functioning correctly, the grinder maintains consistent contact pressure and alignment across the grinding surface. If the lock becomes worn, cracked, or fails to engage fully, it can allow unwanted movement in the secured assembly, compromising grinding consistency and creating a potential safety concern.
